Rules of the road Still nervous about setting out on your own? Don’t be. RV travel will soon feel like second nature after you’ve been doing it for a spell. Here’s a check list of road rules—and some camping know-how—to keep with you as you’re learning the ropes. Always chock your wheels as soon as you arrive at a campground and before you leave your vehicle to explore by foot. Once a trailer is unhooked from a vehicle, it can shift dangerously. Balance and level out the camper to ensure a good night’s sleep. Always triple-check your hookups, and batten down any open windows or hatches before hitting the open road. Stay out of the fast lane unless it’s absolutely necessary to pass a much slower vehicle. Vehicles that are towing trailers are generally illegal to drive in the far left lane.
